WRAP REMOVER Filed Feb 25, 1966 2 sneets-shee 2 INVENTOR BERYL ABOGGSfiywma ATTORNEY United States Patent York Filed Feb. 23, 1966, Ser. No.529,555 2 Claims. (CI. 2820) This invention relates to an apparatus forremoving wraps from moving rolls. More particularly, this inventionrelates to an apparatus for removing wraps from rolls used in fiberdrawing operations. These rolls are referred to hereinafter as drawrolls.

In fiber drawing operations imparting tensile strength to a yarn theyarn is passed over a feed roll, over a separator roll and over a drawroll revolving at a greater rate than the feed roll causing tension inthe yarn. At any stage when the yarn is under tension it can breakparticularly if processing conditions for the yarn preparation were notsufficiently uniform. If the yarn breaks between the draw roll and awinder used for winding the yarn onto a bobbin or the like the newlyformed head wraps around the draw roll several times in an uneven mannerrequiring removal of these wraps. It is standard practice to remove theyarn wraps from the draw rolls with the draw roll in operation andvarious devices are currently in use many of which entail danger to theoperator.

It is an object of this invention to provide an apparatus for removingyarn wraps from rolls particularly rolls used in yarn drawingoperations.

It is another object of this invention to provide an apparatus forremoving yarn wraps from rolls used in yarn drawing operations which canbe utilized without stopping the roll rotation without danger to theoperator.

These and other objects and advantages of my invention will becomeapparent from the following description and claims.

This invention contemplates an apparatus for removing wraps from arevolving roll which comprises a cylinder open at at least one end andadaptable to envelop a roll said cylinder defining window on its side, ascraping means longitudinally slidably positioned on said cylinder androtatable about its own longitudinal axis said means having a protrudingelement adaptable to pass through said window and remove said wraps fromsaid roll into said cylinder and guide means disposed on the surface ofsaid cylinder for postively positioning said cylinder against rotationdue to movement of said roll.

In a particularly desirable embodiment of this invention the scrapingmeans is a rod maintained within a tube rigidly afiixed substantiallyparallel to the surface of the cylinder said rod being slidable throughsaid tube and rotatable about its own longitudinal axis; said protrudingelement is a rigid material such as wood, plastic, metal, or laminatedcomposite structure, said material, where it contacts said roll, beingsofter than the surface of said roll; said cylinder is provided with ahandle atfixed to a plate covering the end of said cylinder opposite theend which envelops the roll; said guide is an annular tube adapted tosnugly accommodate a rigid pin adjacent said roll.

In order to better understand the instant invention, reference is madeto the accompanying drawings in which:

FIGURE 1 is a side elevation of the apparatus of my invention on theleft in relationship to a typical roll assembly on the right for drawingyarn;

FIGURE 2 is a side elevation of the apparatus of my invention inoperating position enveloping the roll and positively positioned againstrotation due to movement of the roll;

FIGURE 3 is an end view of the apparatus of my invention and FIGURE 4 isa perspective view of the apparatus of my invention.

Referring now to the figures, wrap remover 1 comprises cylinder 2 havingon its surface an open window 4. The cylinder is open at end 6 so thatcylinder 2 can envelop roll 8 about which are yarn wraps 10. Roll 8having rotatable flange 12 is mounted on mounting 14 onto which are alsofixed rotatable separator roll 16 and pin 18. Annular tube 20 is rigidlysecured to the surface of cylinder 2 and adapted to accommodate pin 18therein snugly as shown in FIGURE 2. Opposite open end 6 of cylinder 2is rigidly afiixed cover 22 via screws 23 onto which there is provided ahandle 25, only the horizontally extending portions 24 and 26 beingvisible in FIGURES l and 2. This handle permits the operator of theapparatus to align the tube 20 over pin 18 and envelop roll 8 withcylinder 2. On the surface of cylinder 2 is rigidly aflixed housing tube28 through which passes rod 30 on which at the end proximate window 4 ofwhich there is aflixed protruding element 32 suitably constructed ofphenolic laminate. This element is provided with reciprocal threads 34to receive the threads 36 at the end of rod 30. Rod 30 is provided witha handle 38 at the opposite end of threads 36. Handle 38 is reciprocallythreaded at 40 to receive threads 42 on rod 30 so that handle 38 issecure and integral with rod 30. Housing tube 28 is securely mounted tocylinder 2 using screws 44, 46, 48 and 50 passing through extensionplates 52 and 54 which are integral with housing tube 28. Within housingtube 28 are antifriction bearings 56 and 58 suitably ball hearings orneedle hearings forming part of the tube and positioned against rod 30.

In operation the cylinder 2 of the wrap remover 1 is placed over theroll 8 and snugly over flange 12 by aligning tube 20 over pin 18. Tube20 provides a guide for envolepment of roll 8 and flange 12 withcylinder 2. The operator holds the cylinder in place by grasping handle25 with one hand suitably his left hand. With the other hand on handle38 he manipulates rod 30 within housing tube 28 sliding protrudingelement 32 to a position between wraps 10 on roll 8 and flange 12. Theoperator then turns rod 30 about its own longitudinal axis to passprotruding element through open window 4 and in contact with roll 8. Hethen pulls rod 30 in turned position whereby protruding element 32engages yarn wraps 10- and deposits them into the unoccupied volume ofcylinder 2. The cylinder is then removed from enveloping relationshipwith roll 8, as tube 20 is removed from. over pin 18, the yarn is takenout of the cylinder and rod 30 is adjusted to a suitable startingposition.

It is readily seen from the foregoing that I have provided asignificantly useful device for removing yarn wraps from rollsparticularly rolls revolving at high speeds such as that employed infiber drawing operations. It is also apparent that my device shields theoperator from the revolving roll thus protecting him should the yarnwhip about the revolving yarn during wrap removal. Other advantages ofmy invention are obvious to operators who heretofore have been placed ina precarious position when it became necessary to remove yarn wraps fromhigh speed revolving rolls.

The terms and expressions which have been employed are used as terms ofdescription and not of limitation, and there is on intention, in the useof such terms and expressions, of excluding any equivalents of thefeatures shown and described or portions thereof, but it is recognizedthat various modifications are possible within the scope of theinvention claimed.

I claim:

1. An apparatus for removing wraps from a revolving roll comprising acylinder open at at least one end and adaptable to envelop a roll, saidcylinder defining a window 3 on its side, a scraping meanslongitudinally slidably positioned on said cylinder and rotatable aboutits own longitudinal axis, said means having a protruding elementadaptable to pass through said Window and remove said Wraps from saidroll into said cylinder and guide means disposedon the surface of saidcylinder for positively positioning said cylinder against rotation dueto movement of said roll'.

2. An apparatus according to claim 1 wherein the scraping means is a rodmaintained Within a tube rigidly affixed substantially parallel to thesurface of the cylinder, said rod being slidable'through said tube; saidprotruding ele ment is a rigid material being softer Where it contactssaid roll than the surface of said roll; said cylinder is provided witha handle afiiXed to a plate covering the end of said cylinder oppositethe end which envelops the roll; said guide is an annular tube adaptedto snugly accommodate a pin adjacent said roll.
